As part of the campaign, advertisements were placed in newspapers and shown on television, whilst leaflets and posters were put up in GP surgeries.

The campaign is part of the government's £100 million stroke strategy, which was published in 2007.

Health minister Ann Keen said: "Stroke is still one of the biggest causes of death and disability in England. It's important that everyone recognises the signs and realises the importance of dialling 999 as quickly as possible."

"The faster treatment begins the more we can limit damage caused to the brain. The Act FAST campaign has clearly had a big impact already and I hope more people will now see it and learn when to act fast and save lives."
